Smartphones are behind for professional-grade equipment, even though we\u2019re using them more and more for just about everything. So what happens? The quality of our content drops. Convenience always trumps usability, quality, and experience. If it isn\u2019t easy to use, if it isn\u2019t perfectly available and at hand when we need it, then we aren\u2019t going to use it. If you don't need a mic that's quite this small, compare the Spark with our Samson Meteor Mic review. That\u2019s why smartphones are now the most used cameras in the world; the best camera is the one you keep on you. If you're still in the market for the best wireless microphone, take a look at this list to find what's best for you. Or, if you want a microphone that's even smaller than on this list, take a look at our iRig MIC Cast review\u00a0too.\r\nThen again, not everything requires the on-the-go mentality that smartphones provide. Sometimes we just have to sit down and do. Recording audio is a mixed bag; sometimes you need to record an interview, podcast, or voiceover.\u00a0 If this podcast is live, you might want to take a look at the best streaming microphone\u00a0too. The quality should be good, and you shouldn\u2019t be limited by the device you use. That\u2019s where the BlueMic Spark Digital makes it\u2019s debut.\r\nThe Spark Digital is one of the first microphones that connects to both iOS and Android devices, as well as any computer. Through additional cables with MicroUSB or Lightning (there\u2019s also a 30-pin version for iPhone 4\/4S and iPad owners), owners can record very crisp, clear audio from a professional-grade microphone without many of the typical worries that recording on a smartphone brings. Like tapping on a table slightly sounding like an earthquake. Each of the cables also supports connecting headphones via 3.5mm RCA to hear the audio in real time.\r\nInstead of following the typical microphone design, or even BlueMic\u2019s other microphone designs (such as the excellent Yeti Pro, one of my personal favorites), the Spark Digital is a front+rear facing microphone built on a cloth-bound stand with basic pivot movement. The cloth helps to eliminate reverb against the surface, like tapping on the table, picking the phone up off the surface and putting it back, and even tapping on the mic\u2019s stand. Sure, some of these sounds are audible on the Spark, but the cloth muffles them significantly compared to other microphones, where the mic is directly connected by metal or plastic that carries the sound through.\r\nIt\u2019s a small but powerful design that\u2019s made specifically for the mobile-friendly device. Then again, I\u2019ve used the Spark with my desktop to record notes and still picked up and dropped my phone on the same table. We live in an active world, and most microphones aren\u2019t compatible with such noise.\r\nAside from looking really slick -- and it does, with a very strong blue trunk and chrome grill -- the Spark is powered completely by the connected device. It can be disconnected from the base, though the layout of the mic isn\u2019t really suited for carrying around, so I don\u2019t know that it would make sense to carry around for street interviews or the like.\r\n\r\nThen again, the average audio quality is so good, maybe it is. Voices and sounds are recorded with an incredible level of precision, the kind that makes all but trained actors listen and think, \u201cwow, I sound like that?\u201d Audio gain is adjustable right on the mic, plus there\u2019s a mute button so you don\u2019t have to fiddle with your device\u2019s software for a moment\u2019s repose.\r\nAs mobile-friendly as the Spark Digital is, it\u2019s still a high-quality precision microphone. It doesn\u2019t have the flexibility or size to, say, fit in your pocket. It\u2019s not going to replace your phone\u2019s basic microphone for voice memos. The convenience is in not being forced to use a computer with the mic, and that\u2019s phenomenal. I recorded a podcast at my office with the Spark and my iPhone, and it was great. I\u2019ve used it for documentation and got pitch-perfect recordings. It\u2019s the kind that you would expect to hear inside a studio. I\u2019ll be using it for some of our future video reviews, and have already tested and found that it\u2019s perfect for exactly that.\r\nThe travel bag and carrying equipment isn\u2019t great. Three different cables (for iOS, Android, and USB) are excessive; I\u2019d rather see one that works for all three instead. Most people don\u2019t own an iOS and Android device that they\u2019d use for recording, but in the world of mobile, you don\u2019t always use your own phone or tablet. Carrying around three different cables is very inconvenient.\r\nFurther, the bag is pretty thin and doesn\u2019t provide the level of protection I\u2019d expect to see for such a powerful mic. I tried carrying the mic and stand, plus cables, in the carrying bag both standalone and in my messenger bag, and neither felt comfortable. I\u2019d almost rather see a hard-shelled carrying case, though obviously that would take more space. Then again, if you planned on going mobile with your pro-grade recording equipment, a serious case is practically a necessity.\r\nBlue did an excellent job with the Spark Digital. Excellent sound recording, a great design of both the microphone and base, and stunning design absolutely make it worth the $200 price tag.
